Who Pays for My Credit Card Points?
I use credit cards for points, pay the balance every month, and save the rewards for travel and hotel stays. I benefit from the system. I also want to understand who pays for it.
In Episode 15 of The Observation Room, I look at how credit cards became a business, what merchants pay to accept them, and why the reward can get more attention than the borrowing cost. I ask why a much cheaper card hasn’t taken over the market, then work through rate caps, financial education, and the difference between showing someone a price and setting it for them.

Clarifications and sources
Rewards are funded within a business with several revenue sources, including interchange, interest, and fees. Carrying a balance does not by itself tell us why someone borrowed or what they understand. See the Federal Reserve’s credit-card profitability analysis and rewards research.
The economist behind the 1991 paper is Lawrence M. Ausubel. His explanation is one research account of competition, not a complete explanation of every issuer’s pricing. Read the paper’s publication record.
For a lost or stolen debit card, the initial reporting window is two business days after discovering the loss. The separate 60-day window runs from when the statement is sent. Number-only theft has different rules. FTC guide to card fraud protections.
Interchange is only part of a merchant’s total processing cost. The EU’s 0.3% consumer-credit-card interchange cap is not a cap on the full merchant service charge, so it is not directly comparable with a total US processing rate. EU regulation.
At exactly 2.5%, processing $1 million costs $25,000, not $24,000. Minimum-payment payoff times depend on the issuer’s formula and minimum-dollar payment; the episode’s 16-year illustration is not a universal result.
A purchase grace period can help a qualifying cardholder avoid purchase interest by paying in full on time. Cash advances and carried balances work differently. CFPB explanation.
